14.12.TDA1308T
14.12.1.General Description
The TDA1308 is an integrated class AB stereo headphone driver contained in an SO8 or a DIP8 plastic
package. The device is fabricated in a 1 mm CMOS process and has been primarily developed for
portable digital audio applications. It gets its input from two analog audio outputs (DACA_L and
DACA_R) of MSP3411G. The gain of the output is adjustable by the feedback resistor between the
inputs and outputs.
14.12.2.Features
• Wide temperature range
• No switch ON/OFF clicks
• Excellent power supply ripple rejection
• Low power consumption
• Short-circuit resistant
• High performance
• high signal-to-noise ratio
• High slew rate
• Low distortion
• Large output voltage swing.

14.13.MSP34X1G (MSP3411G)
14.13.1.Description
The MSP 34x1G family of single-chip Mullet-standard Sound Processors covers the sound processing
of all analog TV -Standards worldwide, as well as the NICAM digital sound standards. The full TV sound
processing, starting with analog sound IF signal-in, down to processed analog AF-out, is performed on
a single chip. Figure shows a simplified functional block diagram of the MSP34x1G. The MSP34x1G
has all functions of the MSP34x0G with the addition of a virtual surround sound feature. Surround
sound can be reproduced to a certain extent with two loudspeakers. The MSP34x1G includes our
virtualizer algorithm "3D-PANORAMA" which has been approved by the Dolby
compliance with the "Virtual Dolby Surround" technology. In addition, the MSP34x1G includes the
